Thoughts??

If any of yous use this kind of formula how long does these “ready to use” bottles last you?

My baby drinks 5oz every 2 1/2 hours.

One tub of the formula lasts him about a week, then I’m onto another. (Smaller sized tub)

Just wondering what would be better. A 6 pack of the small tubs cost 160$ while these ready-to-use formula cost 39$ a box. Was gonna order 2 of them.
